Go up Button
Forum-Index → Suggestions → Rejected → Go up ButtonSites that I've seen use this feature are usually very heavily based on forums where posts can either be five paragraphs long or a single page can hold a bunch of posts. This site however doesn't usually hold a lot of text/posts on each page of the thread, so there isn't much need for a speedy way to scroll past everything.
And like stated, if you want to get back to the top quickly just refresh. Almost as good as a go up button if not just as good.

Tablets are much like the phone, just with a hint more effort to put into it.
I don't support if I don't see a reason for it, and with how easy most devices make it to scroll up, I don't see a reason for this.
I sometimes use the Touch Pad, and that's easy, too. (like Toothie said, you can quickly swipe down to get to the bottom of the page.)
Unless there is another reason, no.
